To all whom it may concern Brait. known that I, AL EN LOOMIS, a citizen" of the United States, and resident of Det'i 'oit, wayne county, State of Michi gun, have'invented certain new and useful "Improvements in Motor-Vehicles, of which -"wardly extending torque rod 12, suspended T his invention relates to motor vehlcles,

the following is a specification.

and partieulag'ly to means for securing the si'wr'ings of-vehicles to their supports, such as the axle or frame.

One of the salient objects of the invention the production of a spring securing means that will effectively hold the spring to its support, and at the same time be inexpensive to maliulfacture. ,7 w V l Another object of the invention is the production of a spring secnri'ngmeans that yoduction of aspring support in the form elii'ninates the usual shackles with their -un-' nightly projecting ends and nuts.

'tremely ell'ective securing means, and,

designed in this invention, it is simple and inexpensive to manufacture. I V

Referring to the drawings, '10 represents therear end of a motor vehicle frame, and

'11 is the rear or driving axle, having a forat 17, and the latter, or part 16, being secured to the rear end of the frame at 18 and having its end bent around the rear end of the part 15 and suspended therefrom by a link 19. 1 i

By the above arrangement, the driving frmay be shackled to the ir'ame at. 17, and drive taken through radius rods, or

nrongh a properly connected torque rod. As shown particularly inwigs. 2 and 3,

tubular axle at this point, "said members being separated" by Suitable liners pr=..- shims 7 5 action of the axle is-transferred to the frame through the forward end of the spring part 15, and the torque rod 12 sustains-the driving and braking torque of the aide. It will.' be understood of course that the'spring part so I theaxle 11' is ofltubular form near its ends 8% where spring is secured to it, anda pair 10f; bushing! members 20 and 21 surround the 22, .togive proper clearance grease cup. 9:

"23 may be provided; in 'theniember 20, for

the, purpose of keeping these 'relatiYQly mov; ing parts well lubricated. So 'far asthe wedge securing deviceifeature of this invention is coneerned, any'suitable form'of spring stirrups may beprovided, but the invention, as afw hole, is made very'simple and-complete by the use of the particular spring stirrup shown-in this .ap-

plication. This spring stirrup is in the .form F 1 of a continuous or endlessband 24, which is preferably a dro) forgingand this band is formed into an eionga tedrectangle and bent down over the axle or bushing member 2 3, so that it hangs on either side o-f'the axle in the form of loops 25, as shown clearly in one end, r'estsagainst the lower leaf of the spring 15, and hasintegral cars 28 extending upwardlyfat eitherside of the spring. Thus the adapter plate incloses the spring on three sides, and-together with the pad,

, practically surrounds the spring. The pad .26 and the adapter plate27 are each formed at their middle part with depressions 29 and 30 respectively, the depression 2-9 being adapted to receive the head of the bolt 31, and the depression 30 being adapted to resolve the nut of said bolt, which bolt passes through the spring leaics and secures them. together. By this means, the spring is prevented from. moving endwise relative to the spring pad and adapter plate. A plate 32 rests in the bottoms of the loops 25 and is p wided withv lugs 33 at its ends, as shown particularly in Figs. 2 and 7, which lugs project on both sides of the loops 25 and thereby position the plate and hold the loops at the proper distance apart.

Between the plates 27 and 32 is a wedge shaped block 34, which is tapered approximately to the same degree as is the plate 27, and which is formed with a bolt end 35 for drawing it into securing position. A. square washer-36 surrounds the bolt end 35 and contacts with the ends of the. plates 27 and 32, alug or projecting end 37 on the plate '27 preventing the turning oi the washer 36. Nuts 38 on the bolt end 35 are adapted to draw the wedge 34 toward the right in Fig. 2 and thereby clamp .the spring 15 between the loop ends 25 and the pad 25, thus securing the spring under greatpressure between. these elements. 1

The bushing members 20 and 21 and the spring stirrups are prevented. from being moved endwise on the axle 11' by collars 39, adjustably secured on the axle. The spring is assembled by first placing the bushing members and the stirrup in place, then put-- ting the spring endwise through the loops 25, with the adapter plate?! and plate 532 in place, and then forcing the wedge block 34 in between the plates 7 and and tightening the wedge by means of nuts It will be understood that some of the features of this invention are adapted to supporting the spring from the frame. or other parts of the vehicle, as well as from the axle. It will also be understood that other modifications of the invention may be messes made Without departing from the scope support comprising a. continuous band hav-..
